I assume this entry has transferred from the federal Schedule M-2.   If it's not applicable to CA, you can override and remove the description and amount.

This is a ProSeries solution.

PCT has the option to find a check box or line that you want to do input on. CLICK on that line or box and it generally will take you to that input. 

Generally speaking it is not advisable to override an item on the return, unless you are certain the software is doing it incorrectly. Finding where that number came from is your first job.
